Timor-Leste Subnational Rainfall Indicators and Forecasts via CHIRPS

Dekadal rainfall indicators for Timor-Leste are provided at the subnational level by the World Food Programme using CHIRPS v2 and CHIRPS-GEFS data. The records include 10-day, 1-month, and 3-month rainfall totals, averages, and anomalies updated six times per month to transition from forecasts to final observations.

Use Cases

• Assessing drought severity by monitoring the 3-month rainfall anomaly percentage (r3q) across administrative zones
• Planning agricultural cycles using the 10-day rainfall forecast (rfh) filtered by the 'type' column
• Analyzing climate trends by comparing current dekadal rainfall (rfh) against the long-term average (rfh_avg)

Strengths

• Integrates satellite imagery with in-situ station data via CHIRPS v2
• Includes subnational Pcode references for administrative interoperability
• Provides data status tracking via the 'type' column to distinguish forecasts from final observations

Limitations

• Spatial aggregation to administrative units may obscure hyper-local rainfall variability
• Initial dekadal values are based on forecasts and preliminary data which are subject to revision
